Description

Cosmetic composition comprising a linear sulfopolyester and a modified guar gum, and method for using same and uses thereof

Technical Field

The subject of the present application is a cosmetic composition comprising, in a cosmetically acceptable medium, at least one water-dispersed linear sulfopolyester and at least one modified guar gum, and the method of using this composition. The present application also relates to the use of a cosmetic composition comprising, in a cosmetically acceptable medium, at least one water-dispersed linear sulfopolyester and at least one modified guar gum, for fixing the hairstyle.

Background

Cosmetic compositions for styling and/or maintaining the hairstyle may be spray compositions consisting essentially of a solution, usually in an alcoholic solution, and one or more components known as fixing ingredients, usually polymeric resins, the function of which is to form links between the hairs or to coat the hairs. These fixing ingredients are usually formulated in a mixture with various cosmetic adjuvants.

These cosmetic compositions are usually packaged in the form of pump-action sprays, or in suitable aerosol containers pressurized with a propellant; aerosol systems contain a liquid phase (or dispensable) on the one hand and a propellant on the other hand.

Styling compositions in the form of gels, creams or foams may also be used.

Once applied to the hair, the fixative compound should fix the hair.

Indeed, when in contact with water for a long time, for example when in contact with rain or sweat or bathing: in a sea water bath or swimming pools, the polymers generally used as setting agents in setting compositions do not maintain the setting of the hairstyle.
